I agree with that argument, _if_ there are only a few hundred.  I'm also
leaving room for a case here that results in tens of thousands of these
prefixes being routed (for instance, if the community can't reach any
consensus on architectures for many years).

I believe that the RIR's who assign PI space should do so with explicit
agreement that there may need to be a reclamation in the future, when a
new architecture exists.  RIR's do not have the ability to enforce that
today except through some specific policy hurdles and perhaps some fee
structuring.  The primary enforcer will likely need to be service
providers, depending upon the pain they feel from having to carry these
prefixes.
